EVERYDAY STATISTICS

Solution

Arrange the scores in order of magnitude to enable you to note the mode clearly.

100%, 92%, 88%, 84%, 84%, 84%, 84%, 67%, 64%, 54%, 45%, 35%, 24%, 20%, 10%

The mode of the scores = 84%.

We can also prepare a table as follows.

Scores %   Number of times     Scores %     Number of times

100                       1                     45                       1

92                         1                     35                        1

84                          6                    24                        1

67                          1                    20                        1

58                          1                    0                          1
